Water Flanges
Water Flanges covers 11 references held for German, French, Japanese, American and Korean vehicles. Every line is catalogued against its OEM number so a buyer can match a part without opening a box.
The coolant distribution point is where slow coolant loss and boost problems start, and it is also where a wrong part is hardest to spot before it is fitted.

Who This Group Is For
Aftermarket distributors
stocking cooling-system lines for these platforms across a regional network and needing a reference-accurate catalogue behind the shelf.
Workshop and fast-fit chains
replacing water flanges on these platforms daily and judging a supplier on whether the part fits first time.
Online parts sellers
listing by OEM reference, where a mismatched number turns into a return and a negative rating.
What Goes Wrong Without the Right Reference
Returns from wrong fitment
Every returned part costs the freight twice. Checking the port count, the bolt pattern and whether the sensor and seals are included before despatch is cheaper than a credit note.
Long lead times on slow movers
A slow line ordered alone waits for a container. Consolidated with fast movers it travels on the same shipment.
Unclear compound
Compounds differ between visually identical parts.
What the Parts Are Made From
| Material | Why it is used here | References |
|---|---|---|
| PA66 glass-filled nylon | Glass-filled PA66 gives a rigid pipe that holds its shape against vibration and keeps clamp faces dimensionally stable at under-bonnet temperature. | 11 |
Where These Parts Are Fitted
Counter stock for a busy platform
the platform volume in the region justifies holding the line on the shelf instead of ordering it in per job.
Breakdown repair
The vehicle is off the road and the part has to be right the first time, which makes the reference match the whole decision.
Rebuild of an obsolete platform
The original reference is no longer produced, so the part is made from a supplied sample.
Neighbouring Groups on the Same Platform
Cooling repairs rarely stop at one part. These groups travel on the same order.

Water Flanges — Buyer Questions
How many water flanges references are published
11 references are published in this group. They cover BMW and Mercedes-Benz and are listed against the OEM numbers they replace. The wider cooling-system range runs to more than 4000 types.
Which materials are used across this group
PA66 (11 references). Material is listed per reference rather than per group, because two parts with the same outline are often moulded in different compounds.
What should I check before ordering from this group
Check the port count, the bolt pattern and whether the sensor and seals are included. Those are the features that decide fitment on this family, and they are what separates two references that look the same in a photograph.
How quickly can this group be quoted
Email the reference numbers and quantities to [email protected]. A written quotation comes back with packing details and carton counts so you can plan the container load.
Can parts from this group ship with other families
Yes. Mixing intake, charge air, coolant and thermostat lines on one pallet is the normal way this range is bought, and it keeps the freight cost per line down.
What if my reference is not published here
Send it anyway. Publication on this site is a subset of the range, and where a reference is out of production we quote from a supplied sample including mould development.
